Summary:
In Swift, certain for-in loops seem to crash SourceKit. In particular, this is happening while trying to enumerate with a NSAllDescendantPathsEnumerator.
Steps to Reproduce:
1. Create a new command-line tool in Xcode 6.
2. Delete all code from the main.swift file and replace it with the following:
let path = NSURL(string: NSHomeDirectory())
let fileManager = NSFileManager.defaultManager()
let enumerator = fileManager.enumeratorAtURL(path, includingPropertiesForKeys: [NSURLIsDirectoryKey], options: nil, errorHandler: nil)
for urls in enumerator {
}
Expected Results:
Xcode should continue to syntax highlight the code and let me run through each URL in the for-in loop.
Actual Results:
A notification appears in the middle of the screen reading:
SourceKitService Terminated
Editor Functionality Temporally Limited
Version:
Mac OS X 10.9.3
Xcode Version 6.0 (6A215l)
Notes:
Configuration:
MacBook Pro (15-ich, Early 2011)
